Shanghai spot SFA-S2 Bolimo spring reset air door actuator1. Electric multi turn actuator

Electric driven multi turn actuators are one of the most commonly used and reliable types of actuators. Use a single-phase or three-phase motor to drive the gear or worm gear, and then drive the valve stem nut. The valve stem nut causes the valve stem to move and open or close the valve.

Multi turn electric actuators can quickly drive large-sized valves. In order to protect the valve from damage, the limit switch installed at the end of the valve stroke will cut off the motor power supply. At the same time, when the safety torque is exceeded, the torque sensing device will also cut off the motor power supply. The position switch is used to indicate the on/off status of the valve. The handwheel mechanism installed with the clutch device can manually operate the valve in case of power failure.

The main advantage of this type of actuator is that all components are installed in one housing, which integrates all basic and * functions within this waterproof, dustproof, and explosion-proof shell. The main disadvantage is that when there is a power failure, the valve can only remain in its original position. Only by using a backup power system can the valve achieve a fail safe position (fail open or fail closed). 2. Electric single turn actuators are similar to electric multi turn actuators, with the main difference being that the actuator ultimately outputs a 1/4 turn 90 degree motion. The new generation of electric single turn actuators combines the complex functions of most multi turn actuators, such as parameter setting and diagnostic functions using a non intrusive user-friendly interface.

The single turn actuator has a compact structure and can be installed on small-sized valves, with a typical output torque of up to 800 kilograms per meter. Additionally, due to the small required power supply, they can be equipped with batteries to achieve safe operation in case of failure.

3. Fluid driven multi turn or linear output actuators

This type of actuator is often used to operate straight through valves (globe valves) and gate valves, which use pneumatic or hydraulic operation methods. The structure is simple, the work is reliable, and it is easy to implement a fault safe operation mode.

The BF... series actuator is used for controlling small fire and smoke exhaust dampers in ventilation and air conditioning systems. Operating mode: The BF... series actuator rotates the fire and smoke exhaust damper to its normal working position while resetting the spring tension. Once the fire prevention system equipment is triggered, such as smoke sensors, electric switches, or voltage interruptions, the spring will lower and drive the fire smoke exhaust damper to a safe position.

Position feedback: The BF... series actuator has two fixed micro switches used to indicate the positions of the two endpoints of the air door. A mechanical indicator indicates the blade position of the air damper.

Manual operation: The air door can be manually rotated to any position and locked. The mechanical locking device can be manually contacted or automatically released by turning on the power.
